Application 'filed August 27, 191 8. Serial No. 251,614.

To all whom it may concern Be it known that we, HENRY H. l/VALKER and Fm-nu; Enos, J12, citizensof the United States, residing, respectively, at New Lon don, in the county of NewLondon and State of Connecticut, and at Norwich, in the county of New London and State 01 Connecticut, have inventedcertain new and useful Improvements in Deodorizers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention consists in the novel features hereinafter described, reference being showing the attaching plate connected therewith.

The object of our invention is to provide a deodorizer adaptedto be used in connec tion with a ventilating iarunnd especially in.

auditoriums where moving pictures are displayed, theaters and other places ofassemblagc. for the purpose of refreshing, purifying, deodorizing and sterilizing the atinos-i phere of such places of assei'nblage. The atmosphere of moving picture theaters, and. to a. greater or less degree, of other places-of assemblage,where large numbers of people are constantly breathing itior a considerable period of time, becomes very close and inipleasant and various means have been Fig. i is an enlarged detail sectional proposed for. treating the atmosphere of. such places of assemblage, which, however,

have been more or less inadequate or else have "been unduly wasteful of the materials employed or unsanitary, or have required too much personal attention from operatives in order to keep them in operation. It is customary in such places of'assemblage to provide ordinary electrically operated ventilating fans disposed at different parts of the building whichare under control by means of an'electric switch or switches, so that-they can be stopped or startedat will.

One of the objects of our invention is to provide a cheap,simple and eflicient appara-tus which can be readily attached to thc ordinary fan plate housing of any of the many forms of electric fans now on the market and used for such purposes, the apparatus being so constructed that the starting and stopping or" the fanfby means of its controlling apparatus, usually located at a distant point from the ,fan,.will correspondingly start and stop the distribution of a deodorizing, sterilizing, perfuming or othertype of liquid. Another object of our invention is to providefor an exceedingly economical distribution of the liquid employed, which is usually a composite liquid, by forcing a small quantity of air into a liquid containing receptacle located in the path or the current of air from the fanand having a considerable air discharge opening, the air forced into the receptacle being distributed below the liquid level and caused to bubble up through the liquid thereby .agi-

'tatingit so as to preventthe separation of its constituents, and rising from the liquid saturated or charged with portions of all the liquid ingredients, the charged airbeing discharged directly into the much larger volume ofair flowing as an air current from the'fan and being diluted further and infinitely distributed throughout the atmosphere of the auditorium as the operation of the device proceeds.

Another object of our invention is to preventitheloss ofthe liquid employed, when the device is not in operation, by providing the air discharge aperture of the liquid recep'tacle with a closure normally held in closed position by a yielding means, and in connection therewith to employ a blade or vane having a considerable area of surface directly disposed in the air current from the fan so that when-tho fan is started the current of air produced thereby acting upon this vane will effect the opening of the clo' sure. -While the air forcing device may be operated by any desired means, in thesimr V-plest form of the apparatus as herein shown,

we prefer to provide a pin wheel or other air actuated motor operatively connected with the pump and having its vanes-disposed in the path of the air current fromtlie fan so that upon starting the fan the air current will not only openthe closure, as

before indicated, but will also start and continuously operate the pump for forcing air into the liquid receptacle below the liquid level and the pump will be continuously op.--

erated so long as the fan is operating, under ordinaryconditions. i V

Our invention also contemplates the operation of the fan without operating" the airpump and closure controllmg vane or,

blade. This may be accomplished in various ways as, for example, by so constructing the means which holds the closure in closed position, and the' pin wheel or "other form of air motor, that they will not operate unless the fans are driven at a high speed, whereby by lowering the speed of thefan belowthe critical speed necessary to operate these devices, the fan may be permittedto operate without operating 3 the deodorizer,

but this result may be accomplished in other I ways. This, however, is afconvenient means foraccomplishing this result as ventilating fans ordinarily are controlled by'a' rheostat switch so as to be capable of operation at different speeds Vina well known 'way.

' Another object of our invention is to pro- 1 vide for the detachment of theentire apparatus from the supporting plate which 'isfl attached to the fan housing for convenience and also to arrange and construct the pump and air driven wheel therefor so that they may be simultaneously detached from the liquid receptacle for examination or repair,

Referring to the accompanying drawings which, i as before stated, illustrate one emloocllrnent of our lnvention selected by us for the purpose of illustrating the invention, 1

represents an attaching plate which is preferably in the form of a spider having an outer annular portion and a central 13012131011, 2, connected tothe annular portion by suitable arms, 3a The annular portion of this plate is provided with a plurality of slots indicated at 4:, arranged in a clrcle and these slots are provided with retaining devices of any suitable character comprising, in this instance, a hook-shaped bolt, 5, (see Fig. '3) PTOVlClGd'WllZh a wing nut, 6, and washer, 7.

The slots l are so arranged that when the plate is applied concentrically to the housing of any ordinary electric fan the attaching bolts can be so arranged in their respective slotsas to connect the plate with the by a cross bar 9 (see Fig. 8.).

10 represents, the receptacle for holding the liquid to be employe d'and this receptacle is preferably of cylindrical form having its axis disposed horizontally, the'said recep-' tacle being provided with-a bracket arm, 11, adapted-to fit in the socket 8, 9, detachably and support the receptacle and its attached'parts in proper relation wit-lithe revolving fan blades of Lillie fan. The receptacle, 10,1s provided preferably at the 7 top with a longitudinally disposed air charge aperture, 12, whlch is preferably in 0 the form of a slit. The receptacle is also provided, in the form of apparatus herein shown, with a cylindrical casing or seat, 'On its upper face, preferably at one end of the receptacle and within the socket, the re ceptacle is provided with ahole in which is soldered or otherwise secured an air distributing pipe, 1%, which as shown in a Fig. 2 extends down to the bottom of the receptacle and longitudinally (thereof along the bottom and is provided on its upper side with a plurality of air-discharge openings,

'15, ofany desired size andnumber. The

air forcin device, as before stated, is conveniently made separate fron the receptacle and in this instance we haveshown a small pump cylinder, '16,adapted' to fit within the socket, 13, before described, and provided nearits bottoinwith a plug,:17, havlng a plurality of apertures, 18, and provided with a valve, 19, consisting conveniently of a piece of thin leather or rubberattached by a central screw. 20 represents the piston which 1.

coin rises sun 1 a small c lind ical block of metal fittingthe cylinder, 13," and pro vided with longitudinal airapertures, 21, extending from top to bottom, the bottom of the piston being provided with similar,

valve, 22, to the valve, 19, before described. lVe prefer toprovidea bearing bracket, 23, which is formed integrally with or secured to the cylinder and projects from one side thereof and provides two hearings to receive a short shaft, 24, carrying a. small metal pin wheel, 25, alight balance wheel, 26, and a crank or o Y ntric, 27, the latterbeing connected by a link,'28, with the piston, the piston being providedwith a transverse re- "cess, 29, to accommodate the lateral movements of the link or pitman 28. We prefer to use the balance wheel, 26,'as it produces a much steadier GPG'IEIUOHOTE the pn The we may also pro *ide the seat with an addiseat or socket, 13, preferably notched to V 'acconnnodate the bearing bracket, 23, and.

tional notch at another point to receive a guide pin, 30; both these notches serving to prevent any torsional movement of the cylinder with respect to its seat and thecylinder may be conveniently secured in its seat by means of a set screw, 31. The pin, 30, may conveniently be a screw which at the same time holds the valveplug, 17, in the cylinder.

We also provide the air discharge aperture, 12, of the receptacle, 10, with a movable closure to prevent evaporation when the apparatus is not operated and also to exclude dust and other foreign matterivhich might contaminate the liquid. This closure is conveniently made in the form of a curved plate, 32, which in this instance is located on the outside of the receptacle and is curved concentrically with the cylindrical wall which it engages. WVithin the receptacle is, a longitudinally disposed shaft, 33, mounted in bearings, 3a, secured to the wallof the receptacle and provided with collars slipped over the shaft and held in position 0011- veniently by screw threaded pins forming arms 35, 35 which extend up through the aperture, 12, and through apertures in the cover or closure, 32, so as to actuate the closure when the shaft, 33, is rocked. Yielding means are provided for holding the shaft and the arms 35, 35 in such position as to maintain the closure in closed position; for example, an arm 36 is shown adjustably secured to the shaft and provided with anadjustable weight 37 for this purpose. One of the arms, 35, 35, in this instance the arm 35, is extended upward to a greater extent than the other and is provided with an adjustable blade or vane preferably in the form. of a disk as. indicated at 38. Suitable means may be provided on the arms 34, 35, to prevent the closure, 32, from becoming detached, as collars 35 which will not interfere with the easy sliding of the valve ,or closure.

The apparatus hereinbefore' described having been assembled and placed in operative position on the housing of an electric fan, as shown in Fig. 1, itwill be seen that the air discharge aperture of the liquid receptacle as well asthe pin wheel and closure operating blade are within the current of air produced by the fan, the air being permitted to pass freely across the slit or discharge aperture, 12. If now the fan is started the air current therefrom will impinge upon the plate, 38, and open the closure, At the same time the air, pump will be actuated by the pin wheel or other actuating means and will force small (piantities of air through the distributing pipe, 14, causing it to bubble up through the liquid contained in the receptacle, which may be filled to a greater or less extent as desired. These currents of air passing up through, the liquid perform two important functions. These liquids which are used for .deodorizing and disinfecting purposes are usually composed of a mixture of liquid'materials, some of which are more volatile than others, and were the air taken over the top oftheliquid and the liquid permitted toremain quiescent, the components of greatest volatility would be rapidly carwithdrawn from the receptacle will have practically the same properties as the first. These fine air currents charged with the liquid material pass upwardly through the aperture 12 and are caught in the larger current of air passing from the fan which dilutes this charged air and distributes it and the liquid components carried thereby very. widely and uniformly through the atmosphere of the room. When it is not desired to use the device it is only necessary to operate the control switch of the fan so as to stop the fan when the .air pump will immediately cease operating and the weight 37 will cause the closure to move to closed position, thereby preventing any material loss of the liquid in the receptacle by evaporation-or its contamination from dust particles, etc. Thus by starting and stopping the fan bymeans of its usual control mecha "nism the deodorizingapparatus is brought into actionor put out of action without any personal attention being required, it being only necessary to recharge the liquid receptacle fromtime to time.- This may be done by simplypouring the liquid through .the aperture, 12, after openingthe closure 32 by hand, or the device oanbe removed from the'plate 1 for filling and replaced, if desired or found more-convenient.

In some instances it may be desirable to operate the fan without operating the deo (lOIlZQlfg If it is not-desired to detach the apparatus from the fan at such times, the pin wheel and blade, 38,0an be made of such relativelysmall size as not to be actuatedby a moderate current of air so .that the fan may be operated at comparatively. slow speed without bringing the deodorizer into action; while by throwing the fan switch so as to produce a higher speed the deodorizer 1 will be caused to instantly operate. The same result could be obtained in other ways. The form of the invention herein shown and described is very simple, compact, inexpensive to inanufactureand will operate for an i d fin e time Wit er? be g seen. m erially by'wear of parts and is not at; all likely to get out of order. In practice 1t 1s usually found suificientto install these devices on one, two, or more of the usual ventilating fansused in'the place of assemblage. They may, however, be used in homes, offices and other places wherever found convenient or desirable.
